You can put this solution on YOUR website!
There are two ways to do this. Depends on what form you want.
Let's put this in point-slope form.
y-y_1+=+m%28x-x_1%29
highlight%28y%2B22+=+-5%28x-4%29%29 <--- this is perfectly acceptable
If you wanted to go further you could solve for y:
y%2B22+=+-5x+%2B+20
y+=+-5x+-2
However if you had to put it into slope-intercept I prefer this method:

y = mx +b
-22 = -5*4 + b
-2 = b
y+=+-5x+-2
